What are the two main parts of a hurricane?

The two main parts of a hurricane are the eye and the eye wall. Rain bands stretch from the eye wall up to hundreds of miles and carry severe storms and tornadoes.

The eye of a hurricane is at the center of the storm and is relatively calm. Wind speeds within the eye are calm at the axis, and it is typically free of cloud cover. The eye wall is the most turbulent part of the hurricane and contains severe weather due to the constant updrafts and downdrafts. This area is the largest producer of rain, and it extends for miles. As the hurricane increases its speed, the rain bands fit tighter around the eye wall.
